Audi Q5EPC lamp has poor acceleration and no fault code.

Audi Q5epc light is on, and the acceleration is poor. If there is no fault code when reading the vehicle engine system with a computer, this situation may be an accidental fault.

Epc is an electronic throttle fault warning light. In this case, you can go to the repair shop to clean the throttle and the carbon deposit in the intake, and then use the computer to re-match the throttle.

If the fault still exists, it may be that the vehicle engine is leaking air. In this case, it is very important to check the carbon canister solenoid valve and waste gas valve. The probability of failure of these two parts is relatively high.
